红帽全球峰会4.3. 更改管道定义的源分支
默认情况下，当处理推送事件或拉取请求事件时，Pipelines as Code 从触发事件的分支获取管道定义。您可以使用 Repository 自定义资源定义(CRD) 中的 pipelinerun_provenance 设置从 Git 存储库供应商上配置的默认分支获取定义，如 main, master, 或 trunk。
apiVersion: "pipelinesascode.tekton.dev/v1alpha1"
kind: Repository
metadata:
name: my-repo
namespace: target-namespace
spec:
# ...
settings:
pipelinerun_provenance: "default_branch"
# ...注意
您可以使用此设置作为安全预防。在默认的行为中，Pipelines as Code 使用提交拉取请求中的管道定义。使用 default-branch 设置时，管道定义必须在运行前合并到默认分支中。此要求可确保在合并审查过程中对任何更改进行最大可能验证。
